Hi,
try {
String result = null;
ResultSet resultset = null;
PreparedStatement stmt = null;
Connection conn = am.getOADBTransaction().getJdbcConnection();
String qry = "select count(employees) INDIANS from employee where empcountry='INDIA'";
stmt = conn.prepareStatement(qry);
resultset = stmt.executeQuery();
if (resultset != null) {
while (resultset.next()) {
if (resultset.getString(1) != null) {
result = resultset.getString(1);
} catch (Exception e) {
e.printStackTrace();
This will give you the output in variable 'result'.
Now you can set its value to the text input field.

Managing a query result through several web pages

Hi,
I wonder what's the best way to manage a query result through several web
pages in the following context.
The query result is large and needs to be available through several web
pages. The user can scroll forward and backward through the pages.
One can :
- rerun the query at each web request and use random access
- run the query once for the first request, keep the pm and the query
somewhere (in a singleton class for example with a key in the HTTP
session) and use random access for handling the other requests (the
problems I see are to keep a connection for each user in this use case and
to decide when to close the previously mentioned objects)
- rerun the query at each web request, including in the filter a test on a
field and an ordering to start the results from the last one displayed
(being able to specify the maximum number of rows desired would be nice).
Thanks for any advice or suggestion.
Regards.

I think Frank's suggestion is probably the best tradeoff between memory
consumption (which would be high if you were to store the enire query
result in the session) and performance (which might be hurt if you
re-issue the query every time).
Note that Kodo 3.0 will provide a getObjectsById(Object[] ids) method
that should help in quickly instantiating a page of query results.
Query result limiting is currently under discussion for inclusion in the
JDO specification. We may have something for this in an upcoming Kodo
release (although not for 3.0).

(using pm.getObjectId()). We store this list on the session and only
instantiate the objects we need for a particular page (using
pm.getObjectById()). When a user does something that could possibly
change the query result, we rerun the query and replace the list on the
sesssion.--

Retrieving BEx Query Results Area for use in Excel formulas

Hello,
I run BEx queries in workbooks and then use Excel formulas ( mostly VLOOKUP(LookupValue, ResultsArea, ColumnReturned,) ) to retrieve certain information from the query ResultsArea.
****Problem:
Depending on the query parameters, the query "Results Area" is larger or smaller.
****Non-optimal solution:
One way to define the ever changing Excel range occupied by the Results Area is to create an Excel name as:
QueryRange = OFFSET(QueryFirstCell,,,COUNTA(OFFSET(Sheet1!$A:$A,,COLUMN(QueryFirstCell)-1,,)),COUNTA(OFFSET(Sheet1!$1:$1,ROW(QueryFirstCell)-1,,,)))
Then, the only input required is the top-left cell of the Results Area, which stays the same (unless the query definition changes).
****Question
What is the best way to refer to an ever-changing query Results Area in an Excel formula?
Thank you!
Louis

It is actually much easier than that.
Use a VBA statement like the following:
Set RptRng = ActiveCell.CurrentRegion
This will retrieve the data in the Results Area, no matter what the size is.
Hope this helps...

Paged query results in a JSP page

Hi All,
I have a requirement to display only a small number of records (say 50) in a JSP page at a time from a database query that returns more than 10,000 records. For accessing all the other records I have to provide links from the same page. I should be able to go to the first, last, next & previous sets of records at any time. Database is Oracle and the table I am using to query doesn't have a serial number column. Any easy way? Thanks Raj

Hi Raj,
There are two ways to handle it.
One is to fetch the entire set of record from the Database and store the details in a Container which has session level context. But if the fetched size is higher then Session cannot hold that much amount of data.
Alternatively you can go about fetching fixed chunks of data from the
Database(preferably of size 50 to 100). This can be achieved using SQL queries. I have done this and seems to work pefectly in situations where large data available in Database has to be displayed pagewise to the users. (U will find the query in AskTom site of Oracle Corporation).
Please revert back if any further help is needed in this regard.

Need help on retrieving query result - NPE

Hi, I could get results with the native query in my TOAD, but I can't get it working in my session EJB. I tried both native query and EJB ql. The query created fine, as soon as I try to retrieve results, it gets stuck.
My native query looks like this:
Query query = em.createNativeQuery("select sum(o.amount_reimbursed) from t_expenses o where o.employee_id = '999999911' " +
"and o.EXPENSE_ID in (select p.expense_id from T_Per_Diem_Xref p where p.expense_Type_Xref_Id=22 " +
"and p.expense_Id in (select e.expense_Id from T_Expenses e where e.employee_Id='999999911' " +
"and e.expense_date > to_date('01/01/2011', 'mm/dd/yyyy') and e.expense_date < to_date('12/31/2011', 'mm/dd/yyyy')))") ;
My EJB query looks like this:
Query query = em.createQuery("select sum(o.amountReimbursed) from TExpenses o where o.employeeId = ?1 " +
"and o.expenseId in (select p.expenseId from TPerDiemXref p where p.expenseTypeXrefId=?2 " +
"and p.expenseId in (select e.expenseId from TExpenses e where e.employeeId=?1 and e.expenseDate>=?3 and e.expenseDate<=?4))");
query.setParameter(1, employeeId);
query.setParameter(2, expenseType);
query.setParameter(3, fDay, TemporalType.TIMESTAMP);
query.setParameter(4, lDay, TemporalType.TIMESTAMP);
Either one, I get NPE at the line retrieve result.
// sumAmt = (Double)query.getSingleResult();
List list = query.getResultList();
if (list != null) {
long longAmt = (Long)list.get(0);
sumAmt = (Double)list.get(0);
As you can see, I tried to getSingleResult, or getResultList. also tried to convert the result to Double or Long. None worked.
Please help and thank you for your time.
Sophia

Frank, thank you for your reply. I have this code in my session Facade EJB, and I get the NPE in my backing bean which calls this method. When I debug the code, it appears what really cuases the problem is in this code on the line I try to assign the query result to my variable 'sumAmt = (Double)query.getSingleResult();'. In the debug, when it reaches this line, it starts to give me all kinds of pop-up windows saying couldn't find this file or that file or packages. If I get a stack trace later, I will post it. Right now I am trying to fix something else.
Thanks, Sophia

Query Results: Retrieve All Rows?

I was looking for a feature that will allow me to choose to return "all records" to the Query Results window. The current behavior is to fetch 50 records at a time (e.g. fetch 50 records as you scroll through the results = s-l-o-w). What I'd like to do is "Retrieve All Rows" then use to the scroll bar to "smoothly" scroll to the last record. For example, the 8.0.6 version of Query Builder had this functionality and in SQL Developer 3.0, if I right-click on the results. I can choose to "Count Rows...", seems like this would be a perfect place to put a "Retrieve All Rows" option.

Hi,
My advice: do something only if there is a business case for it; satisfying your curiosity can get surprisingly expensive.
You have already read about using Run Statement to execute a SQL statement, then Ctrl-End to auto-scroll to the end. You can try the same for Run Script, but first you will probably need to increase the value of Tools|Preferences|Database|Worksheet|Max rows to print in a script. Of course, taking either of these approaches slows things down due to displaying output and scrolling. Same with SQL*Plus. And, as mentioned previously, Java memory management in SQL Developer can cause slow downs and hangs if the result set is large enough.
Here is a way to minimize that delay, avoid hangs, and get a more repeatable result:
1) Save some query to, say, C:\Temp\AllCustomers.sql. For example, "select * from customers;" or "select id from customers;".
2) Run it from a SQL Developer worksheet using Run Script (F5), or from the SQL*Plus command line, with a script like this:
set timing on
set termout off
spool C:\Temp\AllCustomers.lst
@C:\Temp\AllCustomers.sql
spool offEven then you will see that the timing results will vary. Maybe "select *" runs much slower than "select id" because the logical output lines are long and get wrapped into multiple physical output lines in the file. Minimize that by setting linesize to a longer value (but only in SQL*Plus -- it isn't supported in SQL Developer) and repeat the test to see. Maybe SQL*Plus runs it much faster than SQL Developer because one is a command line environment and the other a GUI tool with more overhead. Or maybe the SQL Developer JVM is near its size limit and lots of Java garbage collection is slowing it down. Simple question, complicated answer.
Regards,
Gary
SQL Developer Team
P.S.: And if by chance you are using a version of SQL Developer so old it does not include the output time in the query result tab's toolbar, using Run Script with set timing on is your only recourse.

Retrieve Query Results in Javascript

Hi,
I've created a SQL query template with Param.1. I've created and iCommand for it. I've also created an Applet consisting of the SQL Query and iCommand template.
I am trying to retrieve query results after setting the parameter. I am getting errors (undefined of course) when using the getValue() method.
1. var commandObject = document.AppName.queryobject;
2. commandObject.setParam(1, var1). var1 = 'Training'
3 applet refresh
4. var var2 = commandObject.getValue(1,1) ==> crashes.
5. alert (var2);
This seems pretty straight forward. Any ideas?
Thanks

How to Open a URL that is displayed in the Column of Results Region in OAF

I need to open Invoice pdf from OAF page. The link to the pdf is obtained from other table.
This is similar to Open Image button that we have in Payables--> Invoice: Entry --> Invoice form.
I need to develop an OAF page where in when the user clicks on the pdf url link, the corresponding pdf has to open for the transaction line.
I have an OAF page for which in the results region, i retrieve a column that contains URL addresses.
Say, I have a column named: URL_ADDRESS (www,yahoo.com) in a table and when i press the search button, all the URL addresses are populated in the results region.
I have defined an item with Style: messageStyledText, and i have set the View Instance and View Attribute properties corresponding to the VO that it is referring to...
What property do i need to set in DestinationURL??
My OAF page is based on pure VO. I dont use EO in my OAF page.

My question is more on how to find the resource from a
particular location.
To be more specific, when I use /myresource/image.gif,
how cat I instuct it
to use the image.gif file which is in myjar.jar?
Thanks.getResource() will search the CLASSPATH for the given resource. If myjar.jar is your application and contains a file "image.gif" in the directory "myresources" gif the above given code will load the image from the jar.

Large query result set

Hi all,
At the moment we have some java classes (not ejb - cmp/bmp) for search in
our ejb application.
Now we have a problem i.e. records have grown too high( millions ) and
sometimes query results in retrieval of millions of records. It results in
too much memory consumtion in our ejb application. What is the best way to
address this issue.
Any help will be highly appreciated.
Thanks & regards,
Parvez

you can think of following options
1) paging: read only few thousands at a time and maintain a index to page
through complete dataset
2) caching!
a) you can create a serialized data file in server to cache the result set
and can use that to browse through. you may do on the fly
compression/uncompression while sending data to client.
b) applet based solution where caching could be in client side. Look in

Thanks Slava Imeshev,
We already have search criteria and a limit. When records exceeds thatlimit
then we prompt user that it may take sometime, do you want to proceed? If
he clicks yes then we retrieve those records. This results in lot ofmemory
consumtion.
I was thinking if there is some way that from database I can retrieve some
block of records at a time rather the all records of a query. I wander how
internet search sites work, where thousnds of sites/pages match criteriaand
client can move back & front on any page.

Hi chauhan,
You may want to narrow search criteria along with processing a
limited number of resulting records. I.e. if the size of the result
is bigger than a limit, you stop fetching results and notify the client
that search criteria should be narrowed.
HTH.

In the execution plan of STEP-3, against ID-1 the operation RESULT CACHE is shown which shows the result has been retrieved directly from Result cache. Does this mean that Oracle Server has Incrementally Retrieved the resultset?
Because, before the execution of STEP-2, the cache contained only 2 records. Then 1 record was inserted but after STEP-3, a total of 3 records was returned from cache. Does this mean that newly inserted row is retrieved from database and merged to the cached result of STEP-1?
If Oracle server has incrementally retrieved and merged newly inserted record, what mechanism is being used by the Oracle to do so?

Edited by: 965300 on Oct 15, 2012 12:25 AMNo, the RESULT CACHE operation doesn't necessarily mean that the results are retrieved from there. It could be being
written to there.
Look at the number of consistent gets: it's zero in the first step (I assume you had already run this query before) and I would
conclude that the data is being read from the result cache.
In the third step there are 4 consistent gets. I would conclude that the data is being written to the result cache, a fourth step repeating
the SQL should show zero consistent gets and that would be the results being read.

How to implement 'Quick Select' column in a query result table?

Hi,
I have a requirement in OAF to design a search page with 'Quick select' column.
One of the column in the query result table should be a quick select.
Once user clicks on the quick select column, we have to navigate back to the previous page with the row value selected.
Can anyone help me in this.
Thanks.

Also refer the search exercise in the toolbox tutorials.
you can implement the quick search in the same way as update and delete buttons.

Query Regarding Query Results in CMC 3.1

Hi,
I want to check what reports are scheduled in particular folder. To get this information we can use query builder by writing a query,but i don't have access to query builder.
Can we check in CMC without access to query builder?I have seen one option In CMC 'Query Results'. What exactly Query results do and how to use.Can this be use to retrieve what reports are scheduled?
Regards
Ranjith

Hi Ranjith,
Query Results option in CMC is an application through which you could create Security Queries. It would help you identify the security setup and access being setup on the objects in your enviornment.

Still some 'Not Assigned' in query result

Hi,
In fact, I've built a query on a multiprovider ( 1 Cube + 1 ODS )
The ODS and the Cube are joined by the material (0material).
The Cube and the ODS are well filled. Queries on each Infoprovider correctly display the results.
When I launch my query on the Multiprovider, it seems the "joined" between the 2 infoproviders doesn't work as
I've still some '#' / 'Not Assigned' value in the query result, and it should give me a result.
In fact the data from the ODS aren't retrieved, they are replaced by '#'. And I don't why ?
Please help.
Thx a lot,
Erwan

Yes you are right.
I made a mistake in my explanation.
But the problem is that the characteristics from the ODS aren't displayed though the characteristic from the cube are correctly displayed.
eg.
In the ODS I've :
( Material, ZCHAR )
'ART01' '315'
'ART02' '412'
'ART03' '999'
In my Cube I've :
'ART01' '12,36' '59,00' '30 ST'
'ART02' '12,96' '89,00' '40 ST'
In the query(on the multiprovider) result I've :
( Material, ZCHAR, other values...)
'ART01' '#' 'Not assigned' '12,36' '59,00' '30 ST'
